| 摘 要： | 利用SAP 2000中的弹塑性时程分析法研究了钢筋混凝土框架结构在双向水平耦合地震作用下的反应,通过与结构在单向水平地震作用下产生的层间位移和层间剪力值大小的对比,分析研究表明:普通的钢筋混凝土框架结构在双向水平耦合地震作用下所产生的层间位移和层间剪力近似是在单向水平地震作用下所产生值大小的2倍,建议在混凝土框架结构的抗震设计中充分考虑地震作用的空间性.

| Abstract: | The elastoplastic time history analysis method is used to study the response of the reinforced concrete frame structures under bi- directional coupling seismic action. By comparing with the inter- story displacement and interlaminar shear force value generated by the reinforced concrete frame structures under the unilateral horizontal seismic action,the analysis shows that the inter- story displacement and interlaminar shear force value generated by ordinary reinforced concrete frame structures under bi- directional coupling seismic action doubles under the unilateral horizontal seismic action. It is suggested that spatiality of the seismic action should be considered in the design of the earthquake resistance behavior of concrete frame structures. |
